In the field of injection mold design you often must develop new and original methods of plastic molding. This sometimes needs a great deal of imagination and inventiveness. What is a normal day like for injection mold design? Most injection mold designers follow a schedule similar to the mold makers. Because their mold designs are soon going to be manufactured from the mold manufacturers, there is a very close relationship between these two.

Like everything else associated with the plastics industry, the answer is yes and no. Yes, because the plastics field is growing all the time and proficient designers are in high demand and reduced supply.

No, because the field is so competitive on a global scale. In this electronic age the designer doesn’t even need to be in the same state as the mold maker.
